OpenSCAD Awesome 3D Rectangular Prism Curved Edge Generator

This is an awesome code I wrote, that very easily, by simply edit a few variables lets you create any size cube/prism you want, and lets you change the roundness of the edges of the prism to almost anything you want. Feel free to copy and paste and implement this into any of your code, and use it how ever you want. I find this code very useful for simple object design.
